(Cl. 43-148) This invention relates to dusting devices for plants and has particular relation to means for separating the dust laden air into a plurality of separate parts for delivery to the nozzles.

In dusting machines, the blower mechanism gathers dust and delivers it to a delivery tube. The delivery tube then conducts the'dust laden air through means for separating the air into as many parts as there are delivery nozzles, the air then passing through small tubes to the nozzles.

In providing means to divide the air volume into equal parts for delivery to the tubes, great diificulty has been experienced in dividing the current of air equally without providing a large number of bulky fittings.

The primary'object of this invention is the provision of an improved device for dividing a tube of'air into a plurality of small streams of equal size and velocity.

Another and further object of the invention is the provision of an improved device for separating an air stream into small streams of a combined cross section substantially equal to the large stream and with a minimum loss due to friction and eddy currents.

Another and still further object of my invention is the provision of a fitting which will receive a cylindrical stream of air, will divide it into sections and deliverit in equal streams of a cylin: drical shape, at its delivery end. j Other and further objects will be apparent to those skilled in the art from a reading of the com plete specification and claims.

The same reference characters refer to the same or similar parts throughout the drawings.

Referring particularly to Figure 1, l desigmates the main frame and platform of a dusting nachine, ll its folding curtain, l2 one of its supporting wheels and I3 its folding rear curtain frame. At its forward, end is located a draft tongue M, which may be drawn by tractor, horses or in any suitable manner. V

Onthe platform I0 is located a hopper l which is provided with a suitably driven beater at its bottom. A blower I1 is located adjacent to the bottom of the hopper 1.5 and is connected thereto by .a suitable passage through which the dust passes; The blower I] is connected to a suitable speed-up gear mechanism I8 which is driven by a drive gear l9. This drive gear I9 is'mounted on the shaft with the pinion 20 which is driven by a power chain'Zl which passes over a power gear 22 mounted on the ground wheel l2.

Connected to the outlet I9 from theblower I9 is a Y-connector 24, to which are connected, inthe embodiment herein illustrated, two distributing nozzles 25. 'In the trated in Figures 1 and 2, these distributing nozzles each have six passages 25 th'erethrough. These'passages at their inlet ends are substanembodiment i1lus'-- tially sectoral in cross section in the preferred i 'form as in the modified form shown in Figure 5.

At their outlet ends which are substantially cir- .cular in .cross section, are passages Mi of fitting 26 which has one passage Mi for and'registering with, each corresponding opening of a passage Inthe passages 25 are secured the ends of the respective flexible tubes 27 which extend to the nozzles 28. There are two tubes 2'! and two nozzles 28 for each row of plants to be treated. In this embodiment illustrated in Figures 1 and 2, there being six passages 25 in each distributing nozzle, provision is made for six rows of plants to be treated on each trip through the field.

In order to raise and lower the nozzles, there is provided a suitable mechanism illustrated in Figure 1. A bar 29 extends across the front of thedusten'to which are connected two rearwardlyextendi'ng'reach rods 36 pivoted at their rear ends to the main frame [0, as at 3|. Secured to the bar 29 are hangers 32 which have at their upper ends, pivoted connections to the lower ends of the links 33. The opposite ends of the links 33 are pivotally connected to crank lever arms 34 which are secured to a crank shaft 35 suitably journaled on the main frame I 0.

A lever 36 is suitably secured to the crank shaft 35 and is provided with suitable dog operating mechanism which operates a dog to cooperate with notches in a segment 3'l.= By operating the lever 36, the height of the nozzles with relation to the plants, may be controlled.

The upper edges of the partitions between the passages are preferably wedge-shape or sharpened at the inlet end as shown at 25 on Figure 2.

7 The openings at the inlet end of the passages 25' are preferably circumferentially spaced about a center" as shownjfor the modification illustrated inpFigure'B. At substantially the center is placed a deflecting point which is illustrated asa conei a 25. This cone 25 acts to divide the fluid current distributing nozzle I25 having eight passages as dust-laden air'into the several parts for delivery to the passages 25.

In 'Figures[ 3, 4, 5, and

6, I have illustrated a This modification is similar in its general construction to the. distributing nozzle already described; The eight passages are provided or ,use on a fourrow duster without the Y'-connection 24 or by using the Y-connection 24, provision isimade for connection oftwo such distributing:

In both 'distributingnozzles 25 and I25; the respective'passageszi's l25 ,1gradual1y change their shape from substantially! sectoral' or pie-. shaped cross section at the' inlet end, to: substanf tially circular cross section at'th'e outlet to provide for connection to thefiexible tubes. 21 already described; The area of cross+sectign of the passages is preferably substantially the same throughout theirrvlengths and the sum of their 'cross sections is preferably substantially equal 'to the cross section of the tube' whichdeliversthe current, andalso to the combined areas of the cross sections of the flexible tubes 21. 7,

It is; thus clear that I have produced a distributing nozzle which is adapted for use on the various types of ,dusters, and which will separate thedust-laden air into the desired numberof partslso that the current will be divided without great losses from constrictions oreddy currents. r I V While I have shown and described in detail embodiments of myinventionit is tolbe understood 7 that the disclosure is merely illustrative and that modifications and changes maybe made withoutqdeparting from the spirit of the invention and within the scope of the appended claims.
